Topic 6.3-6.4 Review: Gene Expression (AP Biology)

What is gene expression?

• The process by which DNA directs the synthesis of proteins.

• The process by which proteins are converted into DNA.

• The replication of DNA during cell division.

• The mutation of genes in response to environmental factors.

What is the process called that uses DNA to create a pre-mRNA?

• Transcription

• Translation

• Replication

• Mutation

What is the modification of pre-mRNA into a mature mRNA called?

• RNA Processing

• Transcription

• Translation

• Replication

What process uses mRNA to create a polypeptide?

• Translation

• Transcription

• Replication

• Splicing

What is the process of making the polypeptide into a functional protein called?

• Protein Folding

• Protein Synthesis

• Protein Degradation

• Protein Denaturation

Where does transcription occur in the eukaryotic cell?

• In the nucleus of the eukaryotic cell.

• In the cytoplasm of the eukaryotic cell.

• In the mitochondria of the eukaryotic cell.

• In the ribosome of the eukaryotic cell.

A Transcription Unit is:

• a segment of DNA that is transcribed into RNA

• a protein that binds to DNA

• a type of RNA molecule

• a cellular organelle involved in transcription

The role of a Promoter in transcription is to:

• bind with transcription factors to initiate transcription

• terminate the transcription process

• translate mRNA into protein

• replicate DNA

Define Gene in the context of transcription.

• A segment of DNA that is transcribed into RNA

• A protein that initiates transcription

• A molecule that carries amino acids

• A cellular structure where transcription occurs

What does a Terminator signal in transcription?

• The start of transcription

• The end of transcription

• The binding of RNA polymerase

• The release of ribosomes
